How To Repair Fork Stanchion Scratch With Epoxy Resin

Crashing on your bike sucks! Especially if you are unlucky enough to scratch your fork, air shock or dropper seat-post stanchion tube. Scratches pass through the seals and can damage them, or can act as a little pocket to collect dirt and grime which can make it's way into the internals. So it's best to repair it if possible.
Note: Repairing stanchion tubes is highly delicate work, great care should be taken, and should only be carried out with specific tools and materials.

I’d probably tape around the epoxy before sanding so I didn’t sand unwanted areas

@Ferrari255GTO Год назад

Technically you shouldn't, the tape would leave a gap between the surface of the stanchions and the epoxy, wich means that once you're done you will have lined up the epoxy with the tape, not with the forks. It would work to get rid of the biggest bump of epoxy but you would need to remove it to finish it properly

@rider65 Год назад

You could use a little petroleum jelly instead of tape to make sure that you don't sand outside the preferred lines and scratch up the stanchions that are not in need of repair.

@cup_and_cone Год назад

In order to properly repair it, you have to feather the repair into the existing coating. There's no way around it...you are going to sand into the coating no matter what.

@Simon1279. Год назад

@@cup_and_cone Agree also because sendhit itself suggests to make the sanding in the sliding direction of the fork for better results and it is what i did and for some magic the anodization after the application of the finishing paste did not show any kind of sandpaper scratch at all.

@fairlyfunctional2236 Год назад

nice. i didn't know there was a fix for scratched stanchions. thanks, anna.

@gmbntech Год назад

Happy to help! Glad you found this one useful! Thanks!

@maxime99991 Год назад

Way too much epoxy resin here... You should use a needle or a toothpick to only apply small amount of resin on the scratches. You would save a huge amount of sanding time. In this kit, they also provide polishing paste that helps to get a very nice and smooth finish. I've used it on my Sid and the result is perfect.

@jvanneste Год назад

We didn’t see a close-up of the result, probably still sanding. 🥹

@mr.z2618 Год назад

She said exactly that. 4:52 . I think it was fine.

@TheJackoelliott Год назад

I've always used hard beeswax melted in to scratches even deep ones . Easy to level out . Doesn't effect the seals and easily replaceable.

@chaselilly8541 Год назад

I'm a mountain biker and a knife maker. The knife making part gives me epoxy experience and I knew as soon as you said epoxy it would work. But not like that. No close ups of the results since I assume you Aldo know you put too much resin. I know from personal experience that much resin take an hour to sand down carefully. I assume you were not careful scratched it up and did not want to show it.

@stormeporm Год назад

So how would you do it with epoxy?

@chaselilly8541 Год назад

@stormeporm the issue was they used too much. I'd do the same but wipe the epoxy off. The scratches would get full with little to sand. Then I'd probably sand stating with 600 lightly until smooth.

@stormeporm Год назад

@@chaselilly8541 Thanks for the info!

@Thehenrybadgeraslan Год назад

I used a Stanley blade to remove any burrs then car body filler and sanded It down with 2000 grit wet and dry. Been fine for 12 months now

@reefbloke Год назад

Now I’ve not done this myself but de-nibbing the resin with a new sharp razor blade( not a Stanley blade) by holding the blade flat to the stantion and slowly de-nibbing the resin without digging into the station should give a finish that requires very little to no sanding . Maybe someone should try this on an older pair of forks as it’s a method I’ve used for years for de-nibbing car paint runs or stone chip touch ups

@KatoTheMaster Год назад

For the Kashima Coating just buy a gold paint pen "UNI Paint Marker is a good match" and add some of it to the mix of the epoxy resin.

@EricvanBallegoie Год назад

Conveniently only wide shots of the 'fixed' fork en no closeups? Putting on huge drops of epoxy and sanding them down with course 150 grit paper will never yield good results. This reallt isn't good advice and I would suggest that you refrain from giving 'expert' advice on subjects you guys are obviously no experts at.

@20CycleMonger Год назад

Good explanation, but No close up of the result? 🤔

@fpeter01 Год назад

Maybe it wasn't that good as you would expext. Haha.

@Near2Future 6 месяцев назад

I just use clear coat that you get in a bottle for touch up jobs. Works well then once set I use a sharp razer to knock off the high spots & make it level no sanding needed. If there is still a little bit i'll use 1500-2000grit more like a polish.

@richardjohnston6688 Год назад

I've done this with sand paper wrapped around a paddle pop stick and dyed black resin and polished the repair and turned out perfect and hardly notice it .

@grayembo Год назад

Sand paper glued or fixed to a plexiglass block would be less likely to bend or fold past the epoxy and scratch the tube. That foam block would be difficult for accuracy.

@enchantedparka3679 Год назад

I use my daughter's enamel nail polish. Works a treat and comes in fashion colors!

@Simon1279. Год назад

Tried this kit on a small scratch on my black stanchion and i would say it really works but: the black resin won't in any way hide the scratch i don't know why. But if you try to feel the scratch with your finger nails you definitely don't, before the treatment i was able to feel the scratch by passing my nails on it. So works great but my own question is: how much will it lasts?

@markmoreno7295 Год назад

Thanks, but you did not mention if there are preventative measures aside from not falling. Ages ago, for example, rubber boots protected the stanchions. Are these bad? Do they even still exist?

@hirokiide7750 Год назад

The early shocks came with the boots (like Mag 20 and Judy) but it turned out people neglected to clean the dirt collected inside and further damaged the stanchions.

@yannickbulliard44 3 месяца назад

The grit size is incorrect in the video. Do not use 150, this would likely ruin the stanchion even more, but 1,500. You can guess in the video that one zero is missing

@SR-gt350 Год назад

That can't be 150 grit sandpaper. Unless it's metric for 1500 grit. I'm thinking 1500 to start and go up to 2000, then 2500

@abtcup Год назад

The missing Kash coat is still an eyesore. You can always go to a hobby shop or craft store to find some matching paint to touch up the Kash before you apply the epoxy.

@rider65 Год назад

Instead of WD-40 or similar use pure silicone to just wipe the stanchion surface off and on top of the Dust seal. Wanted clean you can use a little bit of silicone or suspension grease on the top of the dusty land work the stanchion up-and-down to lubricate and reduce stiction.

Don't think died it never really got off the ground their Tech side of the channel is not really based in science it's just a bunch of guys and gals trying to do ad hoc or on-the-fly repairs. They're not trained mechanics they don't use any science-based methods for testing or application implementation. I mean bless them they try but they usually fail more than they succeed. They just don't do the proper research and if they are doing research there certainly looking and reading at improper incorrect sources information. I'm not sure where they glean their research from but it's usually absolutely garbage. I give them credit for trying but they really do mislead a lot of people on the tech side

@dodgecrockett3474 11 месяцев назад

Are you claiming that a minor scratch could threaten the structural integrity of the fork? As far as I can tell, filling a crevice with epoxy resin has cosmetic value only.

@pauld1848 7 месяцев назад

Scratches would wear down the seal in that spot as well as pull in dust and dirt as it passes the seal. This is the "damage" that would occur from a scratch like this.
